And what does a next generation MeV gamma-ray telescope ... like AMEGO ... cost?A new study proposes that Hawking radiation could be used to find dark matter in places like primordial black holes. … snip … The authors also proposed a technique that could find dark matter by looking for so-called Hawking radiation. … snip … Looking ahead, the researchers believe that the next generation of MeV gamma-ray telescopes would be able to find dark matter in primordial black holes by directly detecting Hawking evaporation.
Just another BILLION dollars (therefore probably far more).
But hey ... money grows on trees, don'tchaknow?
